Cannot run WasmEdge Rust HTTP service

I'm trying to run my independent WasmEdge Rust HTTP example service (ghcr.io/rgl/wasmedge-http-rust-example:0.0.4) under k3s, but it just enters the CrashLoopBackOff state without any obvious clue.

I'm using:

k3s v1.28.5+k3s1
k3s containerd v1.7.11-k3s2
containerd-shim-wasmedge-v1 0.3.0
my k3s playground wasmedge branch https://github.com/rgl/k3s-vagrant/tree/wasmedge (please look at the latest commit to known how containerd-shim-wasmedge-v1 installed and configured)

Please note that it works fine when executed directly by the wasmedge binary as wasmedge target/wasm32-wasi/release/wasmedge-http-rust-example.wasm.

Can you please help me understand why this is happening?

Here's the kubectl describe pods output:
